I need some help.. *.png to *.tex conversion tool

[sigroon365]

I found some source codes that converts *.tex to *.png and vice versa. https://github.com/Inori/SoftwareDevelopment/tree/master/WhiteAlbum
When I compiled it on Visual Studio 2013, lz77 convert *.tex to *.png and png2tex can convert *.png to *.tex.
However, there are some problems. It is different from original *.tex files.

For example, the original size of STING_logo.tex is 90KB, however when it convert back, STING_logo.tex becomes 4,051KB.
So, it causes crash on the game. Here is source code and one sample files. Can someone help me?
